workplaces or to do sightseeing.The introduction of bike­sharing schemes, first developed by new companies like Ofo and Mobike, has brought the trend to a new level.According to data from iResearch Consulting Group, the first week of this year saw 5.85 million active users of Mobike while Ofo had 1.4 million active users.

　　People can unlock the shared bikes by simply using their smartphones.The bikes are equipped with GPS and can be left anywhere in public places for the next user.They're popular among many Chinese people as they provide an effective answer to the "last mile" problem, which refers to a person's final journey."In places where the subway doesn't reach and where it's difficult to change from one kind of transport to another, it's so easy to get where you want to go with Mobike，" Hu Hong, 29, said.She rides a bike to work.

　　However, the schemes have also led to problems such as illegal parking, vandalism (故意破坏) and theft."Bike­sharing is a greener method of transportation and provides a user­friendly experience，" said Liu Xiaoming, Vice­Minister of Transport."But it's a combination of online and offline business.Operators are usually strong in online services, but lack offline business experience."

　　In fact, these problems are also shared by bike­sharing schemes abroad.Set up in 2007, Vélib is a large­scale public bike sharing system in Paris.By October, 2009, a large number of Vélib's initial bikes had to be replaced due to vandalism or theft.Bikes were found hanging from lampposts (街灯柱) or thrown into the Seine River.
